Solution
The correct option is D
light is absorbed and funneled to reaction-center chlorophyll a.
Light is absorbed by various pigments and funneled to the chlorophyll molecule at the reaction center. This leads to the flow of electrons through the ETC, splitting of water and the formation of ATP and NADPH.
